Hey fellow Final Fantasy X explorer! When it comes to side quests, there are a few that you definitely don’t want to miss out on. Make sure to visit the Monster Arena and challenge all the monsters to unlock some powerful abilities for your characters. Don’t forget to hunt down all the Al Bhed Primers for some cool rewards.

Also, if you’re up for a challenge, try completing the celestial weapon quests for each character. It’s tough but totally worth it for the powerful weapons you’ll receive. And lastly, don’t overlook the optional Aeons like Yojimbo and Anima – they can be real game-changers in tough battles. Happy questing!
